Computer controlled vertical universal friction and wear tester MMW-1

Product Details

Computer controlled vertical universal friction and wear tester MMW-1
MMW-1 is a Multi-specimen friction and wear testing machine. It is designed for simulating, evaluating and testing almost all kinds of oil (high-class serial hydraulic oil, lubricant, combustion oil and gear oil) and material (metal, plastic, coating, rubber, ceramic etc.)
It is widely used in tribology field, petrol chemical industry, mechanical, energy resource, metallurgy, space flight, engineering areas, college and institute etc.
